APPARATUS 0R MEANS OF DESICCATING TEXTILE OR OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 268,495, dated December 5, 1882.

Application filed September 7, 1882. (N o modehl To all whom it may concern:

Beit known that I, RALPH S. JENNINGS, of the city of Baltimore, in the county of Baltimore, of the State of Maryland, have invented a new and useful Improvement in Apparatus or Means of Desiccatin g Textile or various other Fabrics, and of recovering or utilizing combustible liquids or vapors escaping therefrom; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a vertical and transverse section, and Fig. 2 a horizontal section, of apparatus embodying my invention, the nature of which is defined in the claims hereinafter presented. Fig. 3 is a representation of a piece of cloth stretched on a drying-frame, as hereinafter explained.

This invention has for its object the expeditious drying of goods or fabrics, particularly such as may have upon them a composition or vehicle containing a volatile oil or liquid-as, forinstance, that class of goods known as gossamer rubber cloth or clothing.

Heretofore it has been the practice to dry such goods in the open air, on account of the essential oil or naphtha arising from them in the process of desiccating them, such being injurious to health, and by reason of its inflamm able character dangerous to life and property when escaping in a building, and, further, the concentration of the noxious or inflammable vapor in a room with the goods to be dried naturally interferes with the process of drying them. Drying of such goods out-of-doors is generally slow and uncertain, depending much upon the state of the atmosphere, and generally requiring extensive drying-frames and much land therefor.

My invention presents a remedy for the difficulties, inconveniences, dangers, and expense resulting from the out-of-doors drying of such articles, and, besides, it affords a means of intercepting and condensing the escaping combustible or noxious vapors, or of utilizing them to advantage. By intercepting and condensing them they. can be again used as before; or, instead of thus treating them, they may with air be driven into the fireplace of a furnace, and thus be burned to aidin produc-' ing heat. t

In carrying out my said invention, I make use in a room, R, of suitable racks, stands, or devices for sustaining the cloth or goods to be dried, and properly exposing the surfaces to air driven against them by the rotary fans.

In the drawings, AA represent two stacks of cloth and their supporting-stands B B, havin g between them one or a series of rotary fans, (J, each consisting of a vertical tube, a, supported by a spindle, b, and provided with a series of wings, 0, extending from it, (the said tube.) This tube hasaseries of openings or perforations, d, arranged in it, as shown, between the wings. Into. the lower end of each tube a the educt c of an air-blower, 1), opens. In each stack the cloths are supposed to be stretched on horizontal frames, and held thereto bytenter-hooks or other suitable means, the several frames being arranged so that the goods or cloths may have spaces between them for the air to pass in cont-act with their upper and lower surfaces. These pieces of cloth are shown atf and their supporting-frames at g.

Between the several rotary fans, or arranged with them, as shown in Fig. 2, are vertical partitions E,whercby the air blown out of each fan will be distributed equally upon the stacks of cloth.

In opposite parts of the room R are vertical tubes F,'having perforations h in their sides. These tubes extend from top to bottom of the room, or nearly so, and open at the lower ends into the induction-pipest of air-blowers Gr, which, with the blowers D, are arranged in a separate chamber or compartment, S, and discharge by educts into or through suitable condensers, H, or instead thereofinto the ash pit or fire-place of a furnace. By means of the condensers the gases or vapors in the air driven through said condensers may be reduced so as to be susceptible of being utilized, as hereinbefore explained.

The operation of theapparat-us may be thus explained. On the blowers and rotary fan or fans being put in action, air will be driven into and out of the hollow tubes of each of such fans, and by its wings will be disseminated through the spaces between the cloths or articles to be dried, and will rapidly evaporate the naphtha or essential oil of the composition of such goods.

The air charged with the vapor will, by the blowers G, be drawn into the tubes F and such blowers, and will be discharged therefrom through the educts 70. Were it not for the exhausting-blowers Gr and the perforated pipes F, the naphtha would collect or be liable to collect in theiupper part of the room, to the detriment of the goods, and the air would not be equally disseminated between the cloths or goods.

From the above it will be seen that the whole process of drying the goods and saving the vapors-of the essential oil or vehicle used in the composition upon them is conducted in a closed room or rooms without the necessity of persons being therein or exposed to the vapors while the process is being carried on. The goods are very expeditiously desiccated, no matter what may be the-state of the outside atmosphere, or the weather be stormy or fair.

What I claim as my invention is as follows:

1. The combination of one or more rotary fans, G, and stationary perforated pipes F, arranged, essentially as described, in a room, R, with one or more induction air-blowers, D, and one or more eduction air-blowers, G, provided ranged, essentially as described, in a room, R,

with one or more induction air-blowers, D, one or more eduction air-blowers, G, and one or more condensers, H, all being substantially and arranged and adapted as and for use as set forth. a i

3. The combination of partitions E,arranged substantially as described, with one or more rotary fans, 0, in a room, R, with such fans, and with the perforated pipes F and air induction and eduction blowers D G, all being adapted and tooperate essentially as and for the purpose set forth.
